My invention consists in a. novel combination of devices, for operationin the one machine, specially applicable to punching and shearing ortrimming the edges of boiler-plates, and whereby the plate isautomatically fediforward, in an intermittent, manner, onor along with asuitablc-bed,.to which it is clamped, and made to pass under an.ordinary or' other suitable punch, and. subsequently, and as the platemoves forward, its edge trimmed by the action of apa'ir of shearsworking in connection with the punch said combination of devices,including means for varying the-length of theinterniittent;feedof thework, causing, it to travel in opposite directions, as desired, orarresting itsti'avelwithont stopping thepunch'or shears, and for feedingit in either direction by a motion derived from thatiof the shears,'an'dirrespective of-the general feed of it, in connection with the punch.

Referring toj th'e accompanyingtdrawingpA is a-bed, to which the plateor work, represented by red lines. in fig. 1, is or niay be secured byclamps a a,- adjnstable along a grooved, made in the top of the bed nearits inner et ge. This-bed is arranged to travel, by a seriesoi'interm'ittent feeds, lengthwise of itselfl in either direction, in oiialong rails cc of a table, B, said bed, or work thereon, crossing orworlring'at right angles to a punch .or punching-apparatus, C,WlIlQiIZIlHty be of the ordinary description used for punching.boiler-plates, and which, where driven by power, may be worked-with abelt, by fast and loose pulleys, d d, on a shaft, e, and. pinion I) onsaid shaft, working into n spur-wheel, E, hung on the operating-shaft ofthe punch. F is atilywhech o nthe shaft e, connec ted with whiohlmay ormay not be a handle for doing light work by hand. 7 G is a spur-wheel,on a secondary shuft,f,-for giving motion to the shears, as hereinafterdescribed.

','lhe feed of the bed A, with the worlc on it, in an intermittehtmanner, so as to bring the work under the punch, at regulator fixeddist-ances apart, is or may be effected automatically, ineither oropposite directions, by or;throngh.reversely-arranged pawls lq h, drivenby, an oscillating-shaft ll, and biting (when in gear) into jteethz'iiri the bed A, only oneof such pawls being in gear at a time, accordingto-the direction in which it is rcq nircd to .rnove-the bed, or, wheniii is required to arrest tl e'tra'vel of the bed, throwing bothpawlsout of gear thcrewit'h, without stopping the motion or the punch or ofthe shaft v i The means for (loingthis'is or linaybeas follows The shaftH is oscillatod by or through a lever, 1, fast thereto, and rod J,connected byan eccentric 01' crank-pin, K, on the punch-operating shaft,which latter may be provided with a sliding clutch, L, for throwing thepunch in or out of-working-action, asdesired.

To vary the length of feed, as established by the pawls g h, accordin'g'to the distanceapart, it is r'eqnired to punch the holes, or othercircumstances.

The red J is connected with th'elevcr I by or through either one of 'aseries of link-pinholes, or otherwise, so as to'give more or less throwto the lever, and consequently increased or diminished'feed to the pawlunder action. The pawls g h are connected to the shaft H'by' beingpivoted to arms/g it, carried by the latteigand are thrown in or out ofgear with their. respeetii'c teeth 2' and j by or through levers, g h,in slotted gear with the 'iaawlsby pins .9 & projecting fromthe latter.These levers- 9 h'f are or may be controlled by a cross rockingj beam, goperateilby a hand-lever, g, through pitman g, in such a manner as that,at a certain elevation of the bandi -lever g, the rocking-beam g, onwhich the free' endspf the levers g it rest, are made to adjust saidleye'rs 9 k, sethat both pawls, j and h are out-of gear with theirrespective teeth, z'j; but on elevating to a given further distance thehand leversgf, the pawl it will be put in gear with its-rack or teethj,' o r, on depress ing said hand-loser to agiven distance below itsfirst-mentioned position, the pawl y will be thrown intogear' withiis'r-ackor-tceth z', th reversely-aeting pawl]: falling by the droppingof its lever la -out (If gear with the -In thiswoy; may the bedA'bestoppedorstarted,aud; run in either -direction bye simple-adjustmentof the hnnd loyer 9 without ehaiigin-g or interfering with" the motionof: he shaft v To keep" the bed A steady in-its forward feed, .which'iswhen operated by ,theipawlig, a'eheck-muvl ordog',
